N UMBERING HAND-STAMP.

SPECIFICATION forming part of Letters Patent N0. 473,605, dated April26, 1892. Application filed July 8, 1891. Serial N0.'398,815- (N model.)

To all whom it may concern;

Be it known that I, OSWALD BARTUSCH, of

Brooklyn, in the county of Kings and State of New York, have inventedcertain new and useful Improvements in Numbering Hand- Stamps; and I dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification.

The object of this invention is to simplify and improve the devices foractuating the pawl-carrier and for regulating its engagement with thenumbering-wheels to effect the desired movement thereof and to improvethe devices for actuating the inking-pad.

In the accompanying drawings, Figure l is a front elevation oftheimproved hand-stamp. Fig. 2 is a vertical section thereof on line a:00 of Fig. 1, with the upper part of the handle broken away. Fig. 3 is asimilar section showing the stamp with the numbering f wheels forceddown to produce an imprint. Fig. 4: is a detailed sectional view showingthe adjustment of the pawls for printing consecutive numbers singly.Fig. 5 is a detailed sectional view showing the adjustment of one of thepawls for producing the impression of each number twice before changing.Fig. 6 is a detailed view, partly in section, of the device foradjusting the position of the pawl-plate.

A is the standard or supporting-frame of the machine; 13, thenumber-wheel frame, mounted in the customary manner to reciprocatevertically within the outer supportingframe; 0, a tubular handleprojecting from the wheel-frame B through a cylindrical collar a on thecross-bar b of the supportingframe A; D, a spiral spring interposedwithin the handle 0 between its upper end and a pin 0, passingtransversely through the collar a and the slots in the handle 0.

E E E are the numbering-Wheels, hung, as usual, upon a shaft F, fixed inthe frame B, each having the customary ratchet-wheel fixed thereto.

G G are the spring-actuated detect-pawls, fitted to the rear side of thewheel-frame to engage the ratchets of the numberingwheels and prevent areverse movement thereof.

The construction of the machine in the foregoing partioulars is notessentially different from that of the approved forms of handstamps wellknown to the art.

The actuatingpawls for the numberingwheels are carried in the usualmanner upon a plate I, (see Fig. 1,) which is pivoted to the front edgeof the transverse bar of the pawlframe-K, consisting of side platesconnected by said bar and severally pivoted to swing at each end of theseries of numbering-wheels upon the shaft F upon which they revolve. Theoscillation of this pawl-frame K required to bring its pawls intoeffective action is produced by the reciprocation of the wheel-frame Bthrough the intervention of a link L, (see Figs. 2 and 3,) pivoted at clto the outer face of one of the side plates of the pawl-frame K at apoint about on a level with the axis of the latter and at e to theadjacent standard of the supporting-frame A at a point below said axis.The pivot-pin at e is made to projectfrom the inner side of the standardthrough an enlarged opening or longitudinal slot in the link, as shownin Figs. 2 and 3, so as to permit of a slight lost motion in the link.

By the use of a short link to connect the pawl-frame with the standardin the machine, as described, decided economy of construction andefficiency of result are obtained. The link L, as it turns on itspivot-pins at cl and 6 while the wheel-frame descends, causes the frontend of the pawl-frame K to be swung upward and backward upon the shaft Fas its axis,'thereby carrying the pawls backward over the ratchets intoposition to make a new engagement with the teeth thereof. When theWheel-frame B moves upward again, the return of the pawl-frame to itsfirst position will so actuate the ratche ts engaged thereby as to turnthe numbering-wheels one step forward. The continued movement of thewheel-frame to complete its stroke after the link has operated to swingback the pawlframe is permitted by the slot in the link, through whichthe pin at e projects. A spring M, (see Fig. 1,) bearing upon thepawl-plate I, operates to keep the several pawls in auto maticengagement with the ratchets.

An independent idle ratchet-wheel N, having a deep notch 42 cut thereinin place of every second peripheral notch, is hung upon the shaft F atone end of the series of numbering-wheels E E in position to be engagedby a pawl P, carried, like the actuating-pawls, upon the plate I. Thepawl P is so proportioned in length relatively to the actuatingpawls asthat when the plate is in normal position and when the detent-pawl Gacts upon the wheel N, as shown in Fig. 5,the said pawl P will operateto hold up the pawl-plate and prevent an engagement of theactuating-pawls with their respective ratchet-wheels when it rests uponthe periphery of the wheel N and will permit such engagement when itdrops into one of the deep notches n. Consequently the numbering-wheelswill be moved only at every second stroke of the stamp and eachsuccessive number will be printed twice before a change is made. Thewheel N is normally held from retrograde movement by the detent-pawl G,and when so held it moves forward one step with each upward movement ofthe wheel-frame, producing the result above described. If thedetent-pawl be held out of engagement with the wheel N, as shown in Fig.4, the said wheel will be moved backward by the contact of the rear sideof pawl P with the rear wall of deep notch 97.. Consequently pawl P willnot rise out of the deep notch and the actuating-pawls will always be inposition to engage with their respective ratchets. The numbering-wheelswill then be moved with each reciprocation of the wheel-frame andconsecutive numbers will be printed.

The means employed for holding the pawl G out of engagement with wheel Nconsists of a cam R, adapted to act upon a shoulder of the pawl. Saidcam is carried upon a rotatable bolt 1", held to rotate and to slide inbearings in the wheel-frame. The bolt also carries near its extremity apin 1*, which is fixed to the bolt at right angles therewith and servesas a handle by which to rotate the bolt and to hold it in one positionor the other by its engagement with shallow notches r and W, the pinbeing pressed into said notches by a spring 0", which acts upon the endof the bolt.

It will be seen from the foregoing that when the pawl-plate is in normalposition and the pin and cam are in the position indicated in Fig. 5 thestamp will duplicate the successive numbers and that when the pawl-plateis in normal position and the pin and cam are in the position shown inFig. 4:, whereby the pawl G is disengaged from the wheel N, the stampwill print consecutive numbers singly. The pawl-plate, however, isprovided with a sliding bolt 2', which may be moved by a knob t" .toengage with a shoulder 2' formed on one of the side plates of thepawl-frame K and thereby hold said plate so that the pawls will notreach the ratchets, as shown in Fig. 8. The reciprocation of thewheel-frame will not then move said wheels and the number thereon whichmay be at the line of print will be repeated at each stroke of thestamp. In this case the position of the cam R and pawl G is immaterial.

It will be observed that all of the devices above referred to arecarried by the wheelframe, by which arrangement it has been possible toattain great simplicity in construction and operation and to reducematerially the size and weight of the stamp.

The inking-pad S is suspended upon the swinging arms S S, pivoted to thesupporting-frame in position to be swung up against the numbering-wheelswhen they are in their elevated position.

In place of the springs and other complicated and cumbersome devicesheretofore employed the arms S S are formed with slots 8 s, which areengaged by pins 3 s,projecting from the sides of the wheel-frame. Whenthe wheel-frame is in its lowest position, the parts will assume thepositions shown in Fig. 3. As the frame moves up and nears its highestposition the pins 8' s will engage at first the closed ends of the slotsand then the upper walls of said slots, bringing the parts into theposition shown in Fig. 2, with the pad resting squarely against the faceof the type. As the wheel-frame descends to make an impression the padis swung outward by the bearing of the pins against the lower walls ofthe slots. When the parts are in the position shown in Fig. 3 with thepins 8' s at or near the limit of their movement, the pad may be swungoutward and upward by reason of the fact that the pin at the lower limitof its motion is free of the slot until it is ex posed in a positionconvenient for cleaning, inking, or replacing. By these means the usualsprings, rods, and levers are dispensed with, the pad is movedpositively by a direct connection with the wheel-frame, and thenecessity of providing for lost motion, in order to secure proper actionof the pad without interference with the movement of the wheelframe, isdispensed with.

I claim as my invention 1. The combination, in a hand-stamp, with itsouter supporting-frame, its reciprocating wheel-frame, a shaft carriedby said wheelframe, numbering-wheels revolving on said shaft andprovided with ratchet-wheels, a pawl-frame swinging freely upon saidshaft, a pawl-plate pivoted to said frame, and pawls carried by saidplate to engage the ratchetwheels, of a bolt carried by said plate andadapted to engage a shoulder on the pawlframe to hold the pawls out ofengagement with the ratchets, substantially as shown and described.

2. The combination, in a hand-stamp, with its outer supporting-frame,its reciprocating wheel-frame, a shaft carried by said wheelframe,numbering-wheels revolving on said shaft and provided withratchet-wheels, a pawl-frame swinging freely upon said shaft, apawl-plate pivoted to said frame, pawls carwheels, a loose ratchet-wheelon said shaft having slots formed therein and open at the I 5 end, andpins projecting from the side of the Wheel-frame and entering saidslots, said pins at their lower limit of motion being free of saidslots, substantially as shown and described.
